CHICAGO (CBS) -- Severe and dangerous thunderstorms brought a tornado to the ground late Sunday night and brought heavy rain and dangerous wind to the entire Chicago area. Monday morning, residents in Naperville and Woodridge area waking up to extensive damage after a tornado touched down.

In Naperville, CBS 2's Jermont Terry encountered many people shaking their heads in disbelief at the devastation – with tree limbs stacked high, and homes boarded up after being cleared out on one side of a street while homes were completely unaffected on the other side. A light pole was even left bent more than 90 degrees from its original upright position.
Indeed, the path of destruction was evident, yet the resilience of the community was overshadowing.
While no tornadoes touched down within the city of Chicago Sunday night, there was some damage in some neighborhoods. In Gage Park near 53rd Street and Homan Avenue, fierce winds did a lot of damage to trees and cars. Volunteers from My Block, My Hood, My City stepped in - working late into the evening to help neighbors.
As of just before 9 p.m., ComEd reported 77 active outages affecting 3,844 customers.
A second tornado has been confirmed as part of the storms that pounded the Chicago area Sunday night and left a path of destruction.
In addition to the EF-3 tornado that hit Woodridge and Naperville, the National Weather Service also confirmed another EF-0 tornado with winds of 85 mph, from just north of downtown Plainfield to Mistwood Golf Course in Romeoville.
Plainfield was where an EF-5 tornado left 29 people dead on Aug. 28, 1990.
Arvind and Savita's house on Princeton Circle in Naperville was leveled by the tornado, but they miraculously survived after being rescued by firefighters. On Monday afternoon, people from all around the area came to the scene to help deal with the devastating damage.
ComEd has restored power to more than 45,00 customers, but 7,000 are still waiting for their power to return. Meanwhile, the City of Naperville reports one home was completely destroyed by the tornado, but 19 have been deemed uninhabitable.
CBS 2 Meteorologist Tammie Souza reports this was also the most significant tornado in DuPage County since June 13, 1976 – 45 years ago.
The damage from the tornado as seen in the Ranchview Drive area in Naperville has been deemed consistent with an EF-3 rating, with peak wind speeds of 140 mph, according to the National Weather Service.
The NWS said this was the first significant tornado -- with an Enhanced Fujita Scale rating of EF-2 or higher -- to impact the Chicago area since an EF-3 tornado hit Coal City in Grundy and Will counties in 2015.
The NWS survey places initial rating at an EF-3 with winds between 136-165 mph.
A total of 14 people taken to hospitals following the tornado, but only two were still hospitalized as of Monday afternoon.
